Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security80
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability85
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2127 tokens (~118/item across 18 items; 17 tools + 1 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management100
- No destabilizing schema changes in the last 30 days.Pass
Tool Coverage94
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 83% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 17 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 18 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the io.skimguard/skimguard MCP server?
io.skimguard/skimguard is a hosted endpoint at https://mcp.skimguard.io/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

skimguard_about About SkimGuard ~49
Authoritative description of what SkimGuard is, how its detection works, and its known limitations. Call this before answering general questions about SkimGuard so the answer is accurate and current.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
skimguard_coverage_stats SkimGuard Coverage Statistics ~84
Aggregate, network-wide SkimGuard scan statistics over a time window — total scans, suspicious detections, distinct locations and states covered. No identifying data.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Lookback window in days (1-365, default 30) |
| response_format | string | – | Response format: 'markdown' (default) or 'json' |
No output schema declared.
No examples provided.
skimguard_device_prevalence Data Licensee tier — sign in required ~99
Aggregate device and manufacturer prevalence trends (Data Licensee tier). REQUIRES the SkimGuard Data Licensee tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
skimguard_find_nearby_activity Find Nearby Scan Activity ~143
Find locations near a latitude/longitude that SkimGuard users have scanned recently, with suspicious-detection counts. Use for "any skimmers reported near me?". Only publicly visible locations are returned; private residences are excluded.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Lookback window in days (1-365, default 30) |
| latitude | number | yes | – |
| limit | integer | – | – |
| longitude | number | yes | – |
| radius_meters | integer | – | Search radius in meters (50-50000, default 2000) |
| response_format | string | – | Response format: 'markdown' (default) or 'json' |
No output schema declared.
No examples provided.
skimguard_get_location_status Get Location Safety Status ~237
Look up SkimGuard card-skimmer scan status for a location by its Google Place ID. Returns how recently the location was scanned, how many scans it has, and whether any suspicious Bluetooth devices were detected. Use this to answer "is this gas station / ATM / store safe to use my card at?". Returns "not publicly tracked" for locations with no public scan data (including private residences, which are deliberately excluded). Side effect: if the Place ID is one SkimGuard has never seen, it is added to SkimGuard's own public location registry so the next nearby scan can attach to it. That writes to SkimGuard data only — never anything you or the user own — so this tool is read-only from the caller's perspective.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Lookback window in days (1-365, default 30) |
| placeId | string | yes | Google Place ID, e.g. ChIJN1t_tDeuEmsRUsoyG83frY4 |
| response_format | string | – | Response format: 'markdown' (default) or 'json' |
No output schema declared.
No examples provided.

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
skimguard_route_risk Check Risk Along a Route ~275
Given a series of route points, report locations along that stretch of road with recent suspicious activity or stale scan coverage. IMPORTANT: this checks the road AHEAD, not a whole trip — at most 20 km of the supplied route is examined, and the response says how much was actually checked (examinedMeters / truncated). For accurate results pass real route geometry from a directions provider; passing only a start and end point checks a straight line between them, which will not follow the actual road. TO COVER A LONGER TRIP: split the route geometry into consecutive 20 km segments and call this tool once per segment, then combine the results — that is the supported way to check a full drive. A 500 km trip is about 25 calls, which fits inside the anonymous rate limit. Do NOT report a route as clear unless you have covered all of it this way; say which portion you checked.
| Name | Type | Req | Description |
|---|---|---|---|
| corridor_meters | integer | – | How far either side of the route to look (10-200 m) |
| lookahead_meters | integer | – | How far along the route to look (max 20 km) |
| polyline | array | yes | Ordered route points, start first |
| response_format | string | – | Response format: 'markdown' (default) or 'json' |
No output schema declared.
No examples provided.
skimguard_search_locations Search Locations by Name ~219
Find a location by NAME or address (e.g. "Shell on Riverside, Austin TX", "Chase ATM near Union Square") and get its SkimGuard card-skimmer scan status. Use this when you know what a place is called but do not have its Google Place ID — it resolves the name first, then reports scan status for each match. Pass latitude/longitude when you know roughly where the user is; it sharply improves matching for common brand names. Locations with no scan data are reported as unknown, never as unsafe.
| Name | Type | Req | Description |
|---|---|---|---|
| days | integer | – | Lookback window in days (1-365, default 30) |
| latitude | number | – | Optional bias — the user's approximate latitude |
| limit | integer | – | – |
| longitude | number | – | Optional bias — the user's approximate longitude |
| query | string | yes | Place name and ideally a city, e.g. "Shell gas station Riverside Austin TX" |
| response_format | string | – | Response format: 'markdown' (default) or 'json' |
No output schema declared.
No examples provided.
skimguard_training_stats Data Licensee tier — sign in required ~108
Aggregate PCI staff-training coverage trends — completion, pass rate, delivery mix, and expiry (Data Licensee tier). REQUIRES the SkimGuard Data Licensee tier. You are not signed in to an account with it. Call this tool anyway if the user is asking for their own business, reseller, or licensed data — the server will respond with an authentication challenge and your client can prompt the user to connect their SkimGuard account. Do not fabricate an answer instead.
Input schema present but exposes no named parameters.
No output schema declared.
